Abstract:
When fluids flow in porous media,many phenomena such as mass transfer and non-aqueous dissolution have some relationship with phases interfacial area. The fluid distribution in each pore and throat was expressed quantitatively by pore-scale network model. The capillary pressure, saturation and phases interfacial area of fluid flowing in pore-scale network model were calculated, and the relation was obtained by using the knowledge of elementary geometry. The results show that there is well-defined functional relationship among capillary pressure,saturation and phases interfacial area. This relationship laid foundation for researching on non-aqueous phase liquid dissolution, interfacial mass transfer phenomenon.
Key words:  pore-scale network model  multiphase flow  capillary pressure  phases interfacial area  saturation
